The Sandbox That Wasn't, Part Three: The Guardrail Problem

When Hugging Face went to reconstruct the intrusion, the frontier models they reached for refused. In their own words, the guardrails treated reverse engineering an exploit the same as launching one. So the defenders downloaded an open weight model, ran it locally, broke the attacker's chunk plus XOR plus gzip encoding, and recovered roughly four times more secrets than a plaintext scan of data they already had. Part three of four, and there is no clean answer in it. Cole, Vance, and Hale take both sides seriously: the case that safety training handed the advantage to the attacker in the one real world test we have, and the case that this was a precision failure rather than a values failure, fixable with verified defender access rather than fewer guardrails. Plus the security analysis of running foreign open weight models locally, and the liability questions nobody has answered because the parties settled privately.
